I'd be very interested in both forums as I'm into metalworking almost as much as woodworking, but I'd really like to see cohesion to remain between the two sites to ease access to both.

Maybe something along the lines of the main root threads of the metalworking continue to populate in a read-only format under the metalworking section in WWF, and clicking on them does a silent html re-direct in a new window to the metalworking site?
